Description

{Pillow differ each parts Height and Multi-hardness and elastomer of Health pillow} which vary the height of head indentation and neck rest according to sleeping position

The pillow of the present invention is composed of a multi-elastic body of a material having a different hardness of the cushioning material of the pillow in consideration of the distribution of body pressure of the body applied to the pillow, in particular the head portion of the sleeper according to the posture of the pillow user lying directly or sideways Considering the difference between the height of the neck and the neck, it relates to a health pillow made of multi-hardness and poly-elastic material, which varies the height of the head recess and neck support according to the sleeping position.

Conventionally, the pillows used in general households have almost constant height and shape without considering any characteristics of the body. Also, by inserting cushion materials such as buckwheat, buckwheat, cotton, rice bran and rice straw into the pillow's envelope, When sleeping, the improper height of the pillow leads to unnatural connection of the head, neck, and shoulders.In particular, the cushioning material in the outer shell does not take into account the distribution of body pressure applied to the pillow by each part of the body. You are pressed by it.

The conventional pillow as described above is unnatural to the sleeping person's posture, the neck or shoulder or waist, etc. are constrained, if severe, neck disk, lumbar disc, etc. may develop, and the cushion material in the pillow is too hard, so the back of the head Under pressure, blood circulation in the cervical vertebrae is not smooth, and the head's head is bruised even after sleeping due to lack of oxygen supply to the brain.

Therefore, many types of pillows have been developed to solve the above problems.

1A and 1B is a pillow focused on improving the cushioning material, the cushioning material 120 is made of oil, gel, gel or urethane foam, etc., and the shell 110 covered therewith is made of a conventional new material fabric. , The middle of the pillow surface is a pillow consisting of a concave indentation of a slightly concave shape and a neck support of a slightly convex projecting shape on one side of the surface, and the pillow of Figures 2a, 2b relates to a pillow with a pad In this regard, it relates to a pillow for adjusting the height by installing the pad 130 on the lower end of the cushioning material (120).

However, the above pillows do not consider the distribution of body pressure on each part of the body and the position of the person lying directly or sideways, that is, the height from the bottom of the head and neck is fundamentally solved the above problems. I could not solve it.

Accordingly, the pillow of the present invention is to solve the above problems, in consideration of the distribution of body pressure of each part of the body applied to the pillow to support the head and neck using a cushion material having different hardness and elasticity depending on the contact area In addition, the height of the head recesses and neck rests located at the center and left and right sides of the pillow, considering that the height of the head and neck of the sleeper is different according to the posture of the pillow user lying right or sideways. It is characterized by providing a health pillow made of multi-hardness, poly-elastic material, characterized in that different.

In general, the pillow's health factors emphasize the shape, height, material hardness, or elasticity of the pillow. Too soft pillows do not support the neck firmly, which makes it difficult to maintain posture and causes many areas to sink into bedding. You will feel less discomfort and less likely to evaporate. In addition, the pillow factors affecting sleep include size, touch, absorbency, hardness or elasticity of the inner material, thermal conductivity, and shape stability. The higher the height of the cervical spine, the neck and shoulders are constrained, the risk of cerebrovascular disease, heart disease, neck disc, the lower cervical spine, the lower back, etc., the neck is also adversely affected liver function . If the head height of the pillow is snoring or scissor sleep, severe wrinkles occur under the neck, and if the head height is low, the mouth is dry, thirsty, nightmare or easily caught cold, ear, throat, lungs There is a risk of the disease.

Therefore, in order to solve the above problems, the present inventors have already filed a pillow of multi-hardness and poly-elastic structure according to the body pressure distribution of each part of the body in Korean Patent Laid-Open No. 02-92275 (2002. 12. 11). The head indentation and the neck rest located at the center part of the pillow and the left and right parts of the pillow, considering the difference in height from the bottom of the head part and the neck part when the person is lying right or sideways. The above problems have been solved by developing a health pillow made of multi-hardness and poly-elastic material, which is characterized by a different height of wealth.
